I've been using my car as a reference ('83 GT original stock 5.0L 4v) and researching old threads about the some emissions systems when I found this thread on the WOT switch and canister purge solenoid activation.

On my 83, the CanPurge solenoids activate when ignition is ON the block hoses from the carb bowls to the charcoal canisters (good thing).
But, the solenoids will deactivate when the WOT switch is "pressed" at full throttle (bad thing).
The CanPurge solenoids should be wired to the hot side of the WOT switch and not the "switched" side of the switch. (?)
84 and 85 models got this right but 83's are wrong ? (from Ford ?) and bottom line is the bowl vents should not be opening at WOT. (?!?)
The correct function of the WOT switch is to activate the bypass solenoid at full throttle/high rpm... which cuts vacuum to the bypass valve which vents smog pump air to the atmosphere at high rpm/full throttle. This is what my car does anyway.
